Abstract: |
The phase change temperature, enthalpy, thermal conductivity coefficient and thermal Infrared properties of the microencapsulated paraffin insulation mortar were studied in this paper. The results showed phase change temperature, enthalpy, and thermal conductivity coefficient of the microencapsulated paraffin insulation mortar were 40～80 , 15J/g and 0.18w/m ℃ ·k ~0.42w/m·k, respectively. The thermal conductivity coefficient decreases with the increase in the dosage of the microencapsulated paraffin. The microencapsulated paraffin insulation mortar has phase-change heat storage capacity for heating by oven, and can maintain its surface temperature stability in a period of time. The surface temperature of insulation mortar was lower 5～8℃ than that of sample without microencapsulated paraffin insulation mortar in outdoor test.
